Low emissions gas turbine engine with inlet air heating
Abstract
Abstract A gas turbine engine includes, in flow series arrangement, a mixer, a compressor, a first flow path of a recuperator, a combustor, a turbine and a second flow path of said recuperator; and a bypass conduit between said turbine and said mixer. A valve is disposed in the conduit and is controlled by a temperature sensor mounted to sense compressor inlet air temperature. The sensor has a set point temperature that corresponds with optimum emissions from the engine. When the sensed temperature drops below the set point temperature the valve opens and hot air from the turbine flows to the mixer where it heats the air entering the compressor. A method for operating a gas turbine engine with preselected emissions over a range of ambient conditions is also disclosed.
